构造器详细资料

AbstractPropertyBindingResult

protected AbstractPropertyBindingResult(String objectName)

Create a new AbstractPropertyBindingResult instance.

参数:

objectName - the name of the target object

另请参阅:

• DefaultMessageCodesResolver

方法详细资料

initConversion

public void initConversion(cn.taketoday.core.conversion.ConversionService conversionService)

getPropertyEditorRegistry

public PropertyEditorRegistry getPropertyEditorRegistry()

Returns the underlying PropertyAccessor.

指定者:

getPropertyEditorRegistry 在接口中 BindingResult

覆盖:

getPropertyEditorRegistry 在类中 AbstractBindingResult

返回:

the PropertyEditorRegistry, or null if none available for this BindingResult

另请参阅:

• getPropertyAccessor()

canonicalFieldName

protected String canonicalFieldName(String field)

Returns the canonical property name.

覆盖:

canonicalFieldName 在类中 AbstractErrors

参数:

field - the original field name

返回:

the canonical field name

另请参阅:

• PropertyAccessorUtils.canonicalPropertyName(java.lang.String)

getFieldType

@Nullable
public Class<?> getFieldType(@Nullable
 String field)

Determines the field type from the property type.

指定者:

getFieldType 在接口中 Errors

覆盖:

getFieldType 在类中 AbstractBindingResult

参数:

field - the field name

返回:

the type of the field, or null if not determinable

另请参阅:

• getPropertyAccessor()

getActualFieldValue

@Nullable
protected Object getActualFieldValue(String field)

Fetches the field value from the PropertyAccessor.

指定者:

getActualFieldValue 在类中 AbstractBindingResult

参数:

field - the field to check

返回:

the current value of the field

另请参阅:

• getPropertyAccessor()

formatFieldValue

protected Object formatFieldValue(String field,
 @Nullable
 Object value)

Formats the field value based on registered PropertyEditors.

覆盖:

formatFieldValue 在类中 AbstractBindingResult

参数:

field - the field to check

value - the value of the field (either a rejected value other than from a binding error, or an actual field value)

返回:

the formatted value

另请参阅:

• getCustomEditor(java.lang.String)

getCustomEditor

@Nullable
protected PropertyEditor getCustomEditor(String fixedField)

Retrieve the custom PropertyEditor for the given field, if any.

参数:

fixedField - the fully qualified field name

返回:

the custom PropertyEditor, or null

findEditor

@Nullable
public PropertyEditor findEditor(@Nullable
 String field,
 @Nullable
 Class<?> valueType)

This implementation exposes a PropertyEditor adapter for a Formatter, if applicable.

指定者:

findEditor 在接口中 BindingResult

覆盖:

findEditor 在类中 AbstractBindingResult

参数:

field - the path of the property (name or nested path), or null if looking for an editor for all properties of the given type

valueType - the type of the property (can be null if a property is given but should be specified in any case for consistency checking)

返回:

the registered editor, or null if none

getPropertyAccessor

public abstract ConfigurablePropertyAccessor getPropertyAccessor()

Provide the PropertyAccessor to work with, according to the concrete strategy of access.

Note that a PropertyAccessor used by a BindingResult should always have its "extractOldValueForEditor" flag set to "true" by default, since this is typically possible without side effects for model objects that serve as data binding target.

• ConfigurablePropertyAccessor.setExtractOldValueForEditor(boolean)
